Focus/Key Topic:



Defined fermentation conditions possess many advantages considering process control and the subsequent downstream. Most often, these conditions are incomparable with natural habitats. For example, pure cultures solely exist within the laboratory. Missing interactions lead to a stunted metabolic profile and silent gene-clusters. Moreover, mixed cultures are beneficial concerning substrate availability and are needed for further process integration.

The Project

Therefore, this project takes a step towards uncovering these advantages. The aim is a defined co-cultivation of the filamentous fungus Trichoderma reesei and a filamentous bacteria e.g Streptomyces coelicolor. Insoluble cellulose serves as substrate, which is hydrolyzed by secreted cellulases of T. reesei. Hence, glucose is made available to ensure growth and secondary metabolite production. The antibiotics actinorhodin and undecylprodigiosin produced by S. coelicolor are of particular interest. By means of co-cultivation an enhanced production and the search for further natural products is targeted.
